Barbecue
and cancer

When
I was growing up it seems like my Dad cooked out every
weekend. To this day, Im convinced that Dads
voluminous carnes asadas must have put cattle, chickens,
and swine dangerously close to extinction, or at least
on the endangered species list. I am not sure if it
was his impecunious childhood, his heartrending experiences
overseas during WWII, or whether he just enjoyed cooking
out over a mesquite fire, but for some reason he always
made enough fajita, sirloin, ribs, chicken, sausage,
and papas y cebollas asadas to feed an extra unexpected
50 guests, should they have shown up. They never did!
On
top of all that carnage, Mom would prepare her delicious
sopa de arroz y frijoles borrachos con bastantes tortillas
de harina, hechas a mano. Dad would cook the tortillas
outside on a big comal over the brasas, after he finished
cooking all the carne. Those tortillas would melt in
my mouth. Back in those days, food processors had not
yet been invented, so when Mom prepared her delicacies,
all the ajo, comino, oregano, chile, cebolla, y tomate,
first went into her molcajete which she then ground
up with her tejolote. Todo a mano.
Monday
thru Friday, Mom made arroz y frijoles for lunch, and
Dad would pick up fresh, hot tortillas de maÏz
from the tortilleria, on his way home for lunch. If
Mom didnt make picadillo or carne guizada to go
with the rice and beans, we ate some of the carne asada
from the weekend. Of course, on Fridays, we abstained
from eating meat, to keep from going to hell, according
to the teachings of the Catholic Church, back in those
days.
Dad
passed away recently and we greatly miss him, but his
legacy of cooking out lives on. I realize that this
column is supposed to be about herbs and maybe lean
a little towards more of a vegetarian diet. But quite
frankly, I am an omnivore. I no longer eat the amount
of animal protein that I used to when I was young, but
I still enjoy a bit of beef, chicken, turkey, fish,
cabrito, wild pig, rabbit, etc., now and then. I keep
my cholesterol below 175mg/dl. For those of you not
familiar with cholesterol levels, thats actually
pretty good. I eat lots of fruits and vegetables, along
with my yerbas. I avoid greasy meats such as mollejas
and tripas, and also manteca in general, and all that
good-tasting stuff.
So
what does barbecue have to do with cancer? Well, by
eating carne asada or barbecue, we actually increase
our chances of developing certain types of cancers,
especially of the colon or breast. This is because an
animal protein called creatine, which is found in red
meat, fish, and poultry, reacts with the high cooking
temperatures of the grill. The resulting compounds are
called heterocyclic amines, or HCAs. These HCAs are
known carcinogens, and they can actually cause normally
healthy cells to become cancerous. Para acabarle de
fregar, cooking over a mesquite fire is even worse,
due to the higher temperatures generated by that particular
type of wood. HCAs are formed within the cooked meat,
and not just on the surface, so it does no good to scrape
off charred outer surfaces. Just to set the record straight,
it is not cooking out over a fire that is the problem,
but rather the high temperatures employed in the cooking
process. The longer that meat is cooked at higher temperatures,
be it grilled, broiled, or fried, the more HCAs are
produced. Thats the bad news.
Now
for the good news: Since HCAs are the product of a biochemical
reaction, altering that pathway can change the outcome
of the reaction. Not cooking the meat quite so long,
and turning it often, will help reduce the formation
of HCAs (of course, meat should be cooked thoroughly
enough to destroy E. coli bacteria that may be present).
Additionally, if the meat is marinated in a very thin
liquid marinade for at least 10 minutes or more, HCA
production will be fur- ther reduced during actual grilling.
The marinades ingredients and its consistency
will determine how effective it will be in reducing
HCA production. Thick, commercial barbecue sauce can
actually triple HCAs, so always dilute thick sauces
before using. Herbs and spices, in general, will reduce
HCA production. This is due primarily to the anti-oxidant
activity that most herbs and spices have in varying
degrees. For example, in recent scientific studies,
a turmeric-garlic marinade reduced HCAs by 50%, while
a teriyaki marinade resulted in a 67% reduction. In
further studies, garlic, rosemary, and sage all helped
reduce HCAs. The antioxidants in citrus will also block
HCA formation. My wife always uses limÚn or naranja
agria plus plenty of spices to season meat prior to
cooking. For those of us who use soy protein, we can
mix a half-cup of textured soy protein per pound of
ground meat before cooking. This can reduce HCAs by
95% without affecting taste. I sometimes make chorizo
with meat and textured soy. Its quite tasty!
The
beneficial compounds in iced-tea can actually help detoxify
HCAs. Im talking about regular green or black
tea, but it must be brewed from loose or bagged tea,
not bottled or instant teas. Iced tea goes great with
BBQ, anyway. You can even make a strong tea to marinate
meat, poultry, or fish, prior to cooking. Since fruits
and vegetables do not produce HCAs, it is a good idea
to grill vegetables along with the meat, and enjoy the
grilled veggies with the grilled meats. I thoroughly
enjoy eating grilled bell peppers, green onions, and
broccoli with my barbecue. Eating plenty of green salads
with the barbecue will also lessen the cancer risk.
That
will about wrap it up for this month. As always, consult
with your physician before using any herbal remedies.

Finally,
here are some easy-to-make marinades that can help make
